Having written the English script, we don’t want anything inappropriate to spoil the play. So would you please spare some time to review the draft script attached to this email and make necessary changes? If it is convenient, may I pay you a visit at your office next Tuesday to give you more details? Given your busy schedule, I’d be very appreciative if you offer to give some professional advice.

As you can imagine, these matter a lot to me. Has anybody happened to find it? Please email me at xxx@googlemail.com Thank you for your time and support.
